ROLLING-MILL.

Patented Nov. 5, 1918.

Application filed September 24, 1917. Serial No. 192,864.

.1 0 (M whom it may concern:

Be it known that I, JEROME R. GEORGE, a citizen of the United States,residing at lVorcester, in the county of Worcester and Commonwealthoflllassachusetts, have invented certain new and useful Improvements inlilolling-ltlills, of which the following,taken in connection withtheaccompanying drawings, is a specification, the present applicationbeing a continuation in part of my previous application, Serial No.868,912, filed October 27, 1914:.

Among the objects of my invention is to increase the capacity of rollingmills, particularly merchant mills, and to enable the product of such amill to be varied in size and dimension, the treatment of said productbeing continuous, as in the usual form of mill, from the heating furnaceto the cooling bed on which the product is finally received.

The above and other objects are accomplished by the novel dispositionand arrangement of the various stands and trains of rolls in a rollingmill. as hereinafter described, reference being had to the accompanyingdrawings in which Figure 1 is a diagrammatic plan view of an arrangementof apparatus which is suitable for the carrying out of my invention.

Fig. 2 is a similar view of the same apparatus in a slightly modifiedarrangen'ient. Like reference characters refer to like parts in thedifferent figures.

Referring particularly to Fig. 1, I have indicated at 1 a portion of aheating furnace, from which the metal is delivered, for coi'itinnonsreduction, to a train of rolls 2, by any suitable delivery means. Thetrain of rolls hereinafter referred to as a roughing train, may consistof any number of stands of rolls for the continuous and progressiveinitial reduction of the metal emerging from the furnace 1, said trainbeing herein illustrated as consisting of four stands of rolls which aredriven by suitable gearing from an independent prime mover, such as amotor 3. ln the line of delivery of the metal from the roughing train 2is prefer ably disposed one or more stands of feed rolls 1. 4, hereshown as two in number, and driven through suitable gearing from anindependent prime mover, such as a motor 5. The stands of rolls servefor the delivery of the heated product, as reduced in section by theroughing train 2, to a suitable guide 6 the metal from the roughingtrain 2 and feed rolls 4, 4.

In common with other mills the present I Fig. 1, such a finishing'trainmay consist of one ormore stands of rolls 7 and 8, and

in the present instance, for convenience of illustration, only one eachof such stands is shown. The rolls of the stand or stands 7 are capableof rotation by suitable gearing from an independent prime mover, such asa motor 9, to move the metal in a direction opposite to its passagethrough the guide 6, which latter may have a suitable curved branch orguide 10 for delivering the metal to the rolls of stand or stands 7. Thestand or stands 8 which form part of this finishing train are adaptedto. receive the metal in a loop 11 from the stand or stands 7, and aredriven by suitable gearing from an independent prime mover, such as amotor 12. The above finishing train elements areduplicated on theopposite side of the line of delivery of the metal in guide 6. by theinitial stand or standsli-S, driven by an independent motor 14, andreceiving the metal through a curved branch or guidelfi, and bv a finalstand or stands 16, receiving the metal by a loop 17 and driven from asuitable motor 18. I

In the operation of the apparatus thus far described, a variety of modesof treat ment for the heated metal may be availed of, by reason of theparticular arrangement and disposition of the stands constituting thefinal or finishing trains on opposite sides of the line of delivery ofthe metal. For instance, if desired, the guideti may be employed toconduct the metal directly to the cooling bed, in its original line ofdelivery from the roughing train 2 and the stands of feed rolls 4, inwhich case said stands 4 will serve as the final or finishing rolls ofthe mill. As herein shown, the guide (3 termiwhich is arranged in theline of delivery of scribed may be run'to gether infseries, jwitl1 'lineof deliver and all adapted to run,

selectively, in t e same or the opposite direction'to the roughing andfeeding rolls, and also to the intimate direction of the metal in thetrain. Such an arrangement is susceptible of numerous immaterialvariations from the forms )roposed herein, especially in the manner oiconducting the metal toward and from the finishing rolls, wherein thegreatest latitude may obviously be availed of, without departing fromthe spirit and scope of my invention, as expressed in the appendedclaims.

I claim, 1

1. In a rolling mill, the combination with feed rolls for supplyingmetal to the rolls of a finishing train, of a finishing train comprisingrolls running in the opposite direction to said feed rolls and spacedfrom the line of delivery from said feed rolls, and

delivery rolls adapted to runin the same direction as said feed rollsand located nearer to their line of delivery than the first mentionedrolls of said finishing train.

2. In a rolling mill, the combination with feed rolls for supplyingmetal to a finishing train, of a finishing train comprising rollsrunning in the opposite direction to said feed rolls and spaced from theline of delivery of said feed rolls, and deliverfrolls adapted to run inthe same direction as said feed rolls, said finishing rolls being instaggered relation to each other, win the delivery rolls nearer to theline of delivery of said feed rolls.

3. In a rolling mill. the combination with feed rolls for supplyingmetal to a finishing train. of a finishing train comprising stands ofrolls on each side of the line of delivery from said feed rolls butspaced therefrom, each of said stands running in opposite directions tosaid feed rolls. and stands of rolls on each side of the line ofdelivery of said feed rolls and nearer thereto than the first mentionedfinishing stands.

4. In a rolling mill. the combination with food rolls for supplyingmetal to a finishing train, of a finishing train comprising stands ofrolls on each side of the line of delivery from said feed rolls butspaced therefrom,

each of said stands running in opposite directions to said feed rolls;and stands of rolls on each side oi the hne of delivery of said feedrolls and nearer thereto than the first mentioned finishing stands, thelast mentioned finishing stands adapted to run in the same direction assaid feed rolls, and being staggered with respect to said firstmentioned stands.

5. In a rolling mill, the combination with feed rolls for supplyingmetal to a finishing train, of a finishing train comprising stands ofrolls on each side-of the line of delivery from said feed rolls butspaced therefrom, each of said stands running in opposite directions tosaid feed rolls, and stands of rolls on each side of the line ofdelivery of said feed rolls and nearer thereto than the first mentionedfinishing stands,

the last mentioned finishing stands being staggered with respect to eachother.

6 In a rolling mill, the combination with feed rolls for supplying metalto. a finishing train, of a finishing train comprising stands of rollson each side of the line of delivery from said feed rolls but spaced-thereir(, m, each of said stands running in opposite directions to saidfeed rolls, and stands of rolls on each side of the line of deliveryfrom said teed rolls but nearer thereto, than said first mentionedstands, said last mentioned stands adapted to run in the same directionas said feed rolls, and being in staggered relation to the correspondingfirst named stands and also in staggered relation to each other.

v7. In rolling mill, the combination with I feed rolls for supplyingmetal to a finishing train, and a guideivay leading from said feedrolls, of a finishing train comprising stands of rolls on each side ofsaid guideway and spaced therefrom, adapted to run in the oppositedirection to said feed rolls, additional stands of rolls on each side ofsaid guideway and nearer thereto than said first mentioned stands, andadapted to run in the same direction as said feed rolls, a cooling bed,a pair of guiden'ays leading from each of said last mentioned stands ofrolls to said cooling bed, and cross guideways connecting said pair ofguideways and placed obliquely thereto.
